adapted for watches, and it consists in theconstructions, combinationsand arrange ments herein described and claimed.

The objects of my invention are to provide a simple and inexpensive formof swivel, which shall be durable in construction and positively lock inclosed position with certainty.

In the accompanying drawings, forming a part of this application and inwhich similar reference-symbols indicate corresponding parts in theseveral views: Figure 1 is a partial sectional view, illustrating oneembodiment of my invention; Fig. 2 is a detailed perspective view,showing the interlocking faces on the hook and latch member, and Fig. 3is a partial sectional view, illustrating a slightly modifiedconstruction.

Referring to the drawings, 1 indicates the body portion of a swivel,which is preferably formed with two legs 2 and 3. A hook 4 is providedwith a headed shank 5 rotatably mounted in the leg 2. The leg 2 is shownslotted at 6 to permit deflection of a portion 7 of its wall intoengagement with the head 8 of the shank; thus locking the shank againstaxial movement. A latch member 9 'is shown rigidly secured to the leg 3,and provided with a head 10 formed .with an interlocking face 11 adaptedto cooperate with the similar face 12 on the hook. A sleeve 13 is shownslidably supported about the latch member 9; the upper and lowerportions of said sleeve being guided, respectively, on the leg 3 and thehead 10. A spring 14 is mounted within the sleeve between the end of theleg 3 and an annular flange 15 on said sleeve. The spring 14 thus tendsto maintain the sleeve 13 in its extended position, with its flange, orstop, 15 in engagement with the head 10.

In assembling the above construction the sleeve 13 is placed on thelatch 9 and the spring 14 positioned within said sleeve, after which,the latch 9 is driven in, or otherwise suitably secured to, the leg 3.pecially in Fig 1, the bore in the leg 3 for receiving the latch member9 is preferably As shown es-- formed with an off-set portion 22 for positively securing the parts together when said latch member is driven intosaid bore. The shank 5 of the hook is inserted in the leg 2, and aportion 7 of said leg is then bent, or deflected, inward into engagementwith the 'head 8 of said shank to prevent axial dis placement of thehook.

It will, therefore, be seen that my invention provides a simple andinexpensive construction which obviates the necessity of employingscrews, or other means, for securing. together the several partsthereof.

Fig. 3 illustrates a slightly modified construction, in which a headedpin 16 is driven in, or otherwise secured to, the leg 2 of the swivelbody portion. In this construction, the hook 17 is provided with ahollow cylindrical portion 18adapted to rotatably embrace the pin 16;said cylindrical portion being slotted at 19 to permit a part 20 thereofto be bent in into engagement with the head 21 of said pin.

The device is operated as follows: The swivel being open, as shown inFig. 2, the hook 4 is inserted in the watch ring. It is then rotated onits axis until the projection 11 on the head 10 enters the opening inthe head 12. In order to permit this, the sleeve 13 is pushed upwardlyagainst the action of the spring. After the hook has been swung intocontact with the member 9, the sleeve is released and permitted to dropover the head 10. The hook 4 is then securely looked.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is:

1. A swivel comprising a body portion, a hook rotatably.secured thereto,means for preventing axial movement thereof, a latch member carried bysaid body portion and provided with a head for engaging said hook inclosed position, a sleeve slidably supported about said latch member forlocking the hook in engagement therewith, a stop carried by said sleevefor engaging the head of the latch member to limit the movement of saidsleeve, and a spring mounted within said sleeve and bearin against saidstop, substantially as describe 2. A swivel comprising a body portion, ahook rotatably secured thereto, means for preventing axial movementthereof, a latch member carried by said body portion and provided with ahead for engaging said hook in closed position, interlocking faces onsaid latch and hook, a sleeve slidably supported about said latch memberfor locking the hookin engagement therewith, a stop carried by saidsleeve for engaging the head of the latch member to limit the movementof said sleeve, and a spring mounted within said sleeve and bearingagainst said stop, substantially as described.

3. A swivel comprising a body portion, a hook having a headed shankrotatably mounted therein, a deflected part of the body portion arrangedto enga e the head of said shank for preventing axial movement thereof,a latch member carried by said body portion and provided with a head forengaging said hook in closed position, a sleeve slidably supported aboutsaid latch member for looking the hook in engagement therewith, a stopcarried by said sleeve for engaging the head of the latch member tolimit the movement of said sleeve, and a spring mounted Within saidsleeve and bearing against said stop, substantially as described.

4. A swivel comprising a body portion, a hook rotatably secured thereto,means for preventing axial movement thereof, a latch member carried bysaid body portion and provided with a head for engaging said hook inclosed position, a sleeve slidably su ported about said latch member forlocking t 1e hook in engagement therewith, an inner annular flan ecarried by said sleeve for engaging the head of the latch member tolimit the movement of said sleeve, and a spring mounted within saidsleeve and bearing against said flange, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
